Embodiment 1

[0026] The object of treatment is well water in the suburbs of a certain city in Hunan. The arsenic content in the water is 2ppm, and the COD Mn It is 8ppm, and the conductivity is 450us / cm.

[0027] Put the polarity reversing switch 7 in the positive gear, put the filter element in, open the water inlet cover 9, pour the well water into the well water unit 1, and replenish the water halfway for purification. After the purified water storage tank 6 is filled with a certain amount of water, stop To work, the polarity reversing switch 7 is placed in the off position. Pour out the purified water through the water outlet for analysis, the arsenic content is 0.03ppm, COD Mn It is 2ppm, and the conductivity is 160us / cm.

[0028] After three consecutive uses, the arsenic content is 0.05ppm, COD Mn 2ppm, conductivity 380us / cm, to regenerate the electro-adsorption unit, take out the filter element, pour clean tap water through the water inlet, put the polarity reversing switch 7 in th...

Embodiment 2

[0031] The treatment object is the tap water of a city in the north, the chromium content in the water is 0.6ppm, the COD Mn It is 4ppm, the nitrate is 25mg / L, and the conductivity is 520us / cm.

[0032] Put the polarity reversing switch 7 in the positive gear, put in the filter element, open the water inlet cover 9, pour tap water into the well water unit 1, and replenish the water halfway to perform purification. After the purified water storage tank 6 is filled with a certain amount of water, stop working , put the polarity reversing switch 7 in the off gear. Pour out the purified water through the water outlet for analysis, the chromium content is 0.05ppm, COD Mn It is 1ppm, the nitrate is 5mg / L, and the conductivity is 180us / cm.

[0033] After three consecutive uses, the chromium content is 0.05ppm, COD Mn The nitrate is 1ppm, the nitrate is 18mg / L, and the conductivity is 410us / cm. Regenerate the electro-adsorption unit, take out the filter element, pour clean tap wate...

Abstract

The invention relates to a portable drinking water purifying apparatus and a use method thereof, and belongs to the field of drinking water treatment. Tap water is poured into the above treatment apparatus and automatically flows into a filter unit to adsorb organic matters and remaining chlorine and to realize ion exchange resin adsorption of heavy metals and parts of salts, and obtained tap water enters an electro-adsorption unit to further purify heavy metals, perchlorate radicals and nitrate radicals in order to obtain purified water; and the filter speed of a filter core is fast, and the heavy metals and the salts are mainly removed through electro-adsorption, so the use period of the filter core is far longer than that of a traditional pitcher, and a lithium battery is used to drive electro-adsorption salt removal in order to realize desorption reuse, thereby the cost is low. Compared with present reverse osmosis water purifiers, the portable drinking water purifying apparatus adopting the method in the invention has the advantages of extremely low apparatus investment, portability and extremely low cost; and compared with present pitchers, the apparatus adopting the method in the invention has the advantages of low treatment cost, long service life of the filter core, and good quality of treated water.

Description

technical field [0001] The invention belongs to the field of drinking water treatment, and in particular relates to a portable drinking water purification device and a using method thereof. Background technique [0002] Due to industrial development and population growth, the discharge of industrial and domestic sewage has seriously polluted surface water and groundwater. Drinking water contains organic matter, heavy metals and other pollutants, exceeding drinking water standards. On the other hand, chlorine-containing disinfectants commonly used in tap water will react with trace organic matter in the water to produce carcinogenic disinfection by-products such as vinyl chloride. Even if the green disinfectant ozone is used, harmful chlorates and bromates will also be produced. Disinfection by-products. Therefore, the tap water supplied by conventional water plants is difficult to meet the requirements of daily drinking, and the safety problem of drinking water is relativel...
